Aluminum 5052

Aluminum 5052 is a non-heat-treatable aluminum-magnesium alloy known for its excellent corrosion resistance, formability, and weldability. Compared with 6061, it offers lower strength but performs better in humid, marine, and corrosive environments, making it particularly suitable for sheet metal, enclosures, and lightweight structures.

Appearance & Properties

Color: Silver-white to silver-gray

Density: Approx. 2.68 g/cm³

Tensile Strength: Approx. 210–260 MPa (common H32 temper)

Corrosion Resistance: Excellent

Machinability: Fair

Weldability: Excellent

Formability: Excellent

Surface Finishes: Anodizing, bead blasting, brushing, polishing, powder coating, painting, etc.

Typical Applications

Aluminum 5052 is widely used in marine, automotive, electronics, sheet metal fabrication, transportation, and industrial equipment.

Typical parts include equipment enclosures, electronic chassis, sheet metal panels, marine components, tanks and containers, vehicle panels, brackets, and lightweight structural components.

Advantages

• Excellent corrosion resistance

• Good forming and bending performance

• Excellent weldability

• Lightweight and suitable for sheet metal structures

• Well suited for humid and marine environments

Limitations

• Lower strength than 6061, 6082, and 7075

• Fair CNC machinability

• Cannot be significantly strengthened by heat treatment

• Not ideal for high-load structural components
